CHARLES BURNHAM, OF LGS ANGELES, CALIFORNIA, ASSGNOR TO BURNHAM BASKET COlJPANY, [i CORORA'IIN OF CALFORNIA.

BOX-AKING MACIINE.

Application filed February a, 1915.

To all 't0/1.0m 'it 'may Concern Be it known that I, CHARLES BURNHAM, a citizen of the United States, and a resident of Los Angeles, county of Los Angeles and State of California, have invented certain new and useful Improvements in Box- Making Machines, of which the following is a full, clear, and exact description.

This invention relates more particularly to the punch and die mechanism of a machine for making berryl or fruit baskets such as shown in my pending application, Serial No. 734,155, filed November' 29, 1912.

One of the principal objects of the invention is to provide means whereby shocks of veneer or other material may be supported crosswise and folded into box form without the necessity for scoring the shocks and without causing or permitting the shooks when of wood to break or sliver at the point of folding particularly where the shocks,

as is often the case, are cross-grained, and

which means during the folding operation will move the box body in its folded form in position to receive ametal or other suit able binding to complete the box.

Another object of the invention is to provide yieldingly held wings as a part of the die mechanism and which so co-act with other parts of the die that during the folding the shocks or body material will be positively held at the point of folding and the wings made to lap or slide at such fold ing point, thus making a perfect fold.

Other objects of the invention are to provide the die with yielding parts which will compensate for any error in lengths of the shocks and which will feed the shooks if of uneven lengths properly into the binding rim and hold the same while the bottom of the basket takes care of the error in the difference in lengths of the shocks and still allow a good basket to be made; to provide simple means for absorbing the inaccuracies in alinement and also any difference in the thickness of the wood or other shocks; and to provide adjustments between the several parts of the die mechanism and to hold the same againstl improper movement.

A further object of the invention is to provide a simple and effective plunger or punch which is adapted to cooperate with the die, and which assists in forming the box body Specification of Letters Patent.

Patented Auw. 15, 1916.

Serial No. 6,109.

and further assists in stripping the box body when formed.

A still further object of the invention is to provide simple means whereby parts of the plunger or punch mechanism may be removed for repairs or for other purposes.

A. still further object of the invention is to provide simple and eflicient means whereby suction may be created or destroyed in a part of the die to assist in stripping the box when formed from the punch and keep the box down in the die and place the same in position for removal from the machine.

A still further object of the invention is to provide simple and eflicient means for holding the shocks crosswise for removal and folding by the punch and die.

l/Jith these and other objects in view, the invention will be hereinafter more particularly described with reference to the accompanying drawings, which form a part of this speciiication, and will then be pointed out in the claims at the end of the description.

In the drawings, Figure 1 is a vertical section, partly in elevation, of one form of punch and die and mechanism embodying one form of my invention and showing a shook holder or carrier located between the punch and die for supporting the shooks crosswise of each other. Fig. 2 is a fragmentary vertical section showing one form of means for creating suction in the die. Fig. 3 is a view similar to Fig. 2 except that the parts are in a different position. Fig. i is an enlarged vertical section, partly broken away and partly in elevation, of the die and mechanism shown in Fig. l. Fig. 5 is a fragmentary section showing a form of adjustment between certain parts of the die mechanism. Fig. 6 is a fragmentary side elevation of the adjusting means shown in F i 0. 5. Fia'. 7 is a vertical section taken on the line VII-VII of Fig. 5 showing how the adjustable links are held spaced apartin pairs. Fig 8 is a plan view, A, artly in section and partly broken away, of the die and its mechanism and the guide frame for the die. Fig. 9 is a sectional plan taken on the line IX-IX of Fig. 4. Fig. l0 is an enlarged vertical section, partly broken away, showing the punch or plunger and the die in position after the shocks have been folded into box form, the position of some of the parts being' somewhat exaggerated for illustrative purposes. Fig. is a fragmentary section showing how the mechanism may be made to clench the metal rim or binding to the box form with a dovetailed effect. Fig. 11 is a vertical section of the punch showing the means for operating the same as well as the mechanism for pinching the binding` about the box form. Fig. 12 is an inverted plan view of the punch or plunger. Fig. 13 is an enlarged view, partly broken away and partly in section, showing the clencher mechanism. Fig. 14 is an enlarged fragmentary section of the punch and parts in their normal position. Fig. 15 is a fragmentary section of a part of the punch or plunger. Fig. 15a is a fragmentary sectional plan showing how two screws of the punch may be held from turning. Fig. 1G is an inverted plan of the punch and clencher mechanism partly broken away. Fig. 17 is a view of a spring clip or latch for the metalbinding. Fig. 1S is a fragmentary section, partly in elevation, of a fixed form of latch or catch for holding the lapped. ends of the binding prior to Vclenching the same to the box form. Fig. 19 is a fragmentary elevation of the form of latch shown in Fig. 1S; and Fig. Q0 is an inverted side elevation of the cam portion on one of the clenching members which is adapted to depress one of the folders for the metal strip while the strip is being forced about the anvil or former.

lliile the invention is ordinarily applied to a particular form of machine, it will be understood that many of the features may be used in connection with various forms of box or basket machines or alone, and that some of the parts may be dispensed with or other features substituted therefor without departing from thc spirit of the invention.

In the general operation of an automatic box-making machine to which this invention is particularly applicable, a narrow metallic strip is fed from a reel or other wise suitably supported convenient to the machine, and this strip by suitable mechanism is fed to what may be termed forming mechanism, that is, the metal is bent or formed lengthwise thereof so as to be substantially V-shaped or U-shaped in crosssection in order to lit over the open edge of the box form. This strip is fed inward and tilted and after being tilted so that it will assume a proper position relative to the edges of the box and the anvil or former about which it is bent according to the shape of the box, the strip is then cut off the proper length. The strip is then fed forward on one side of a substantially rectangular anvil having a shape corresponding to the shape of the open end of the box and luntil the said strip meets the anvil,

when the jaws into which the strip has been previously fed by engagement with the former or anvil will bend both ends of the strip on opposite sides thereof making the same substantially U-shaped. A. second pair of jaws engages the free ends of the binding strip and forces the same on the remaining side of the anvil and causes one end of the strip to overlap the other. The shooks of which the box body is made are placed in two magazines located adjacent to one end of the machine, and these shooks are automatically fed upward in position to be removed therefrom. A reciprocatory and rotary pneumatic device is provided for this purpose and this device is automatically controlled so that the shooks will be picked up lirst from one magazine and then from the other so that the shooks as thus picked up will lie crosswise and at substantially right angles to each other. The pneumatic device discharges the crossed shooks into a rotary carrier or turret. A movement is given to the carrier and this places the crossed shooks in the path of box-forming mechanism, and at the proper time this mechanism operates to form the shooks into box form and carries the box from above the carrier and forces the upper edge thereof into the binding strip. The -bind ing strip is then pinched on to the shooks thus holding the box shooks permanently together in box form. Means is provided for stripping the box and 'causing the completed box to be deposited into the carrier, and the carrier as it feeds new shooks crosswise to the die mechanism conveys the completed box into position to be discharged. The completed box is forced out of the carrier into a chute and properly stacked and may be removed in any desired way. jinother form of machine to which the invention is applicable is one in which two or more strips are used as a binding' for each box or basket, or as already stated, the invention may be used simply as a hand operated or box body forming machine.

rlhe veneer-shooks are placed in a holder 1() in any suitable way between a punch or plunger 11 and the die 19.. The holder if) may be of any suitable kind or may bein the form of a carrier which is adapted to move the shooks in a crosswise position under the punch 11 and then to receive the completed box and move the same away from the punch and die in substantially the manner described in connection with the application hereinbefore referred to. 1nstead of the movable holding means for the shooks as set forth in said application for holding' and alining the same, the' said shooks ,maybe sprung or forced between stationary grippers 13 and 14C. There are two substantially L-shaped grippers 13 and two similar grippers 14C arranged in opposed relation and eacli has a retaining lip or bead 14a. rl`he sets ot grippers 13 and 1l are. so arranged that When the shooks are forced therein they Will lie one at a higher level than the other so that any diiierencc in their lengths will not cause the top shook to spring the one beneath it down so tar that the latter will be away irom its regis# tei-ed position in the gripper-s. rl`hese shoohs are indicated at 15 and 1G and are adapt-ed, as will be hereinafter described, to be held between the plunger and die and to be moved by said plunglr and die ,trom the holder 10 and formed into box form.

The die and its operating mechanism, Figs. 1 and il to 111-, comprises a head 17 substantially rectangular' in. form and having a concaved upper sui-tace in which is seated a rubber gasket or pad 18 also substantially rectangular' in form. rThis pad is held by a plate 19 which extends partly over the upper surface or" said pad. The plate 19 has a central opening and through said opening extends a tubular reiv 20, the threaded end of which engages the threaded upper opening of a tubular member 21 in which suction may be created or a vacuum formed so as to create suction about the pad 18 as will be presently described. The screnT Q0 Well as the upper surface ott the plate 1Q are each provided withv radiating grooves adapted to communicate with the tube or member 21 so that suction may be created over substantially the entire surface ot said suction pad 18, Ait the outer edge of the pad 18 are yielding members rllhere are tour of such members so as to make a substantially rect-angular body When in position which corresponds substantiallyT to the shape ot the boi; or berry basket bottom. rllhese members are substantiallyT L- shaped in form and have one portion thereot movable in recesses 23 in the die head 17 and said members 22 are normally forced outward by springs 34-, located in said recesses 23, the outward movement oi said members being limited by means oiE screws Q5 or in any other desired Way. rllhe purpose ot' these yielding members 22 is to compensate tor any irregularity in the length o't the shooks when inserted into the binding as will be described hereina'tteiu the said plates or members 22 yielding su'liicientlv to permit the sides of the box when 't'olded to be 'forced slightly downward in order that the upper edges ot the box may be substantially straight and in order that the narrow metal binding may be properlv held to the upper edges of the shocks to form the boX.

A Wing or member 26 is adapted to cooperate With each or the yielding members 22 and as there are tour of the yielding members Q2 and four ends of the shocks to told there are also tour wings 26. rlhe ends of the shocks which lie crossvvise are adapted to have their outer ends rest on said wings QG and at the outer edge ot' the Wings are yieldingly held members7 plates or parts :27 which have a relative movement and which are adapted to aline or cause the shoolrs to be properly registered. rlhe ineinbers 27 have a tongue-and-groove connection `with the wings and iii'ieldingly 'forced outward by springs 38 or otherwise7 said outward movement being limited by stops 28 held to the ,.ier surtace of each plate 2T and adapted to eng ge the outer ond ot the wing on `which the p1 27 moves. rlhe springs Q8 are located on i outside oithe plates 27 and are interp lugs on said plates and lugs c tbe wings 2G. The inner edges of the Wings 26 are substantially semi-circular and are adapted to underlap the outer edges oit the members @o outer edges ot the 5 id members 22 and with a lapping etect yieldingly hold and more about the shoolrs at the told so that the latter cannot sliver or break even should the hooks be oit cross-grained Wood. The inner ends o1 the Wings are provided with recesses which receive the ends 29 oit springpressed bolts 30. rlfhese bolts, tivo for each vving, have their loiver ends passing through apertures in lugs 30LL on the die head, and around said bolts are springs 30b tending normally to torce the saine outwardly and to yieldingly hold the inner edges ot the wings 25 against the outer edges of the members Q9. said springs having seats in recesses or ccncaved portions in the heads ot the bolts 3G at one end. and having seats in the lugs 30 at their other ends or in cupshaped devices it prelerred. A pluraiity o't spring clips 30C are provided each having two retailing `lingers which are adapted to partly spur` the heu ds oit two ot the bolts 30, there being a clip tor each pairI oit bolts 3f) of each Wing.

To move the die upward and also to more the wings QG to told the shor'il-:s and iorin the sides thereof, various means may he employed. is shown. the wim )A3 are provided with lugs 31 and conne d to these ends oil the arms E are err yted bv plus 32 to a cross-head i323. the inner portion ot which is provided with an opening in vf'bioh is held a tubular member -t. the latter being arranged around the central Juhu meniber 9,1 and being held to the cross-hea d 23? by means of a nut 35 or in any other des ed way. Tivo linls or arms 3G are connected to each pair ot arms 3?! at one rnd and to the die head 1'? at the other end. and said lV .lis are adapted during the upward movl` oi the crossdread E32-l to hold the arms 2lij i such a manner as to ed between .-5.

so that in their npn Yrd folding inove u. i g endl-ic elle sani@ er) nlm o properly about the outer edge of the plates or members 22 during the folding operation. rllhe cross-head 3S has outwardly extending arms 37, the outer portions ol which are pivotally connected by tubular pins 38 to arms or links 39. The pins 38 are held to guide blocks l0 which are adapted to move vertically in guides Mlfl forming a part oit a boxlike structure 42, the said parts serving to prevent any rotary movement ot the die as the same is moved upward. The lower ends of the links or rods 3S) are connected to arms Ll?) and these arms are pivotally held to a shaft fil- These arms are connected to be operated by an arm l5 which is connected to a link or rod elli. The rod i-6 is connected at its lower end `to an arm i7, and said arm is pivoted at Li8 to the machine frame, said rod LlG being provided with a turnbuckle i9 by which the latter may be adjusted. rlhe arm 47 is provided with a trundle 50 which is adapted to be operated by a cam 51 arranged on the drive shaft 52. The die head 17 has downwardly extending portions which are connected by tubular pins or thimbles to the upper ends of links or rods T he lower ends of the rods are connected to arms 55 and these arms are operat-ed 'through an arm 5G which extends outwardly and moves about the shaft llll as a pivot. The arms 5G is coimected to a link or rod 57, the lower end of which is pivoted to an arm 58 which adapted to rock on the shaft 48. The arm 5S like the arm Li7 is provided with a trundle 59 which is adapted to be operated by a cam (SO, said rod 57 beingl also provided with a turnbuckle 6l by which the latter may be adjusted. lt will be evident that as the shaft is rotated7 the cams will operate the arms i7 and 5S and will move rods fl-G and 57 so that the die head 17 and the cross-heaf will move in unison and at the proper time during the upward increment owing to the character oi the cams 5l and GO? the arms will cause the wings 26 to be moved at an angle with respect to the upper surface ot the die, thus forcing the ends oit the shocks uiviwardly to fold the same. lnstead oit' the particular mechanism described for operating the die, any suitable mechanism may be employed.

rlhe punch 11 has a part thereof bodily movable downward toward the die so that the shocks may be held between the die and the punch and by the punch and die the shocks are carried upward and during such upward movement folded into box form. rlhis punch l1 has a presser toot 62, a inemher (32%, and a third member Gel. The member (il is held to a head G5 and about said head is an anvil (lll which is substantially rectangular in i'iorm and about which the metal binding strip is formed so that its open edges extend downward as shown best in Fig. l0. The member Gfl has yielding sides 67, the lower edges of which are provided with ribs 68 which are adapted to be seated in grooves in the upturned portions G9 of the body 70 of said member 64, though instead oit said movable sides, the said member may be solid. Each side is normally pressed outward by one or more springs 7l and such outward movement is limited by one or more screws 72, the threaded portion ot which is held in the body portion 70 of the member (Si and the head of which is seated in a bushing or cup-shaped cap 73 which may be spun into an opening in each wing or side 67 so that said sides may be permitted to yield properly under the pressure or the plates 27 and die wings or members 2G when the latter are forced to the position shown in F ig. 10. The screws 72 may be locked from turning, F ig. 15a, by a ball 73 which is arranged to engage the inner portions of two ot th-e adjacent screws 72, said ball being forced inwardly by a screw 73D at the same time forcing the unthreaded ends of the screws 72 against the unthreaded walls 73C of the body 70. The member (il of thel punch has a relatively slight up-and-down movement, while the member 63 and presser toot 62 move toward the die and then upward again7 although said presser foot 62 has a relative movement with respect to said member G3. This presser foot (32 has a body 74 substantially rectangular in form and while somewhat smaller corresponds to the shape or the bottom o't the box or basket to be made and has a tubular stem 7 5 which is adapted to slide within the tube 7G, there being a key or wedge 77 which passes through a slot 78 in the stem 75 and serves to draw the member (33 up tight on the tapered end of the tube 76. rIhe presser i'oot serves as a stripper l'or the member G3 to keep the bent part of the shooks from wrapping around or adhering to said member when the latter comes out of the box when formed. rl"he presser foot is normally forced downward by springs 7 9 arranged.between the upper surface oi the body 7l or" said foot and a ilauge at the upper portion of the member (lh the said springs being arranged around rods projecting upward from the presser foot and which serve to hold the springs in position. The member 63 or' the punch or plunger has a tapered opening centrally thereof which fits upon the tapered end ot' the tube or guide 7 G. The tubes 76 and 80 extend upward through a part 8l of the machine frame and at the upper end of the tube 76 is a yoke 82 which is rigidly held to the tube 7G and is adapted to have a vertical reciprocatory movement imparted thereto by means of levers 83 or othen wise so that the member 63 with the presser toot 62 may be forced down to meet the die soY and to engage the shocks and then to move upwardly with the die again carrying the shocks therewith. 11s previously stated, the shoolrs lie crosswise in the holder 10 so that one will be at a higher level than the other in order that any diterence in their lengths will not cause the top shook to spring the one beneath it down so tar that the latter will be away from its registered position in the fixed grippers 14. rlhese shooks may be moved from the iixed grippers without breaking the ends thereoi'r'. rhe die should be closed to approximately thirty degrees, and said die in its upward movement passes through the holder 10 and during such movement the ends of the shooks will draw in and will be 'treed from the grippers, it being understood that the punch coperates with the die at this time. rlhe die can continue to rise and should there be any tendency for the shocks to slip more to one side than the other, a little tension bar, not shown, extending out of the die may be employed to hold the shocks between it and the punch to keep the shocks from moving or revolving. The tube S has a collar or head Se against which rests the upper end et a spring 85, the lower end of said spring resting against apart 86 ot the frame portion 81. rlhe spring 85 serves to force the ubc S0 and the anvil G upwardly when released as will presently be described.

ils the shocks are folded into box form as shown in Fig. 10, the upper edges therei are received in the open portion of a substantially rectangular metal binding substantially *e-shaped in cross-section which is held and supported in any suitable way about the anvil 66, the particular construction ot anvii and the means whereby the strip or strips are formed rectangularly thereabout, not forming a part of the present invention, may be of any desired construction or may be such as disclosed in the application herein reif-erred to. After the metal binding has received the upper edges ot the boX form, suitable clencher mechanism, as 87, may be employed to clench or crimp the narrow metal binding about the edges ot' the box form. As one means, l provide levers 8S which may be pivoted, at 89, to a head 90 or part of the trame, and

- at their lower ends, said levers carry adinstable presser or clencher jaws 91. rThe upper ends of these levers 88 may be held by springs and have a toggle connection with the sleeve 92 by means of links 93, said links being kept from coming out by screws 93a. The sleeve is independently movable upon thc tube 80 by means of levers 94 or otherwise so that at the proper time the metal strip or strips about the anvil is forced into locking engagement with the boit form.

After the strip is clenched about the box body, the die is lowered and as the die is lowered the box or basket is carried therewith and may be deposited into four corner holding members 94e, Fig. 1, substantially f-shaped in torni and mounted in the holder 10, or the boxes may be otherwise disposed ot' as preferred. To assist in removing the bei; or basket from the punch, I provide suction means. This suction means may be accomplished in any suitable manner. As shown, the suction pad 18 which is held by means or the plate 19 and tubular screw 20 against the die head 1? is adapted to tit snugly against the bottom ot the basket and suction is created within the tube 21 in such4 a way and at such a time that the basket will be caused to be held to the bottom of the die and with the assistance of the presser toot 62, the said basket when completed will be forced or stripped from the punch. The tubular screw has radial slots 95 which are adapted to register with slots 96 in the plate 19 so that when suction is created within the tube 21, air may be drawn through said slots 96 to create suilicient suction to hold the box shocks to the die bottom and said suction should be destroyed at the proper time to adapt the box to be removed automatically or otherwise. The tube 21 is provided with an opening 97 and this opening is adapted to register with an opening 98 in a tube 341 arranged around said tube 91. rlhe tubes 21 and 3-1 are movable in a tubular part 99 of the machine frame. This tubular part 99 has an extension 100 to which may be connected an exhaust pump and within the member 99 around the tube 3d is chamber 101. This chamber 101 is adapted topbe placed into communication with the openings 97 and 98 to canse suction about the box or boX material as shown in Fig. 3. The suction or vacuum is adapted to be destroyed by a relative movement between the tubes 91 and 34 as shown in Fig. 2, and a small opening 101a in a plug 102 located in the bottom ot the tube 21, which opening is of such a size as will not injuriously affect the suction means while in operation and while the ports or openings 97 and 9S are in alinement but which will destroy any vacuum in the tube 21 as soon as the suction means is cut orf, there being an adjustable thimble or sleeve 102a provided whereby the time when the suction is destroy-ed through the opening 98 may be properly timed. lnstead ot' the ports and the parts as shown, any suitable means may be employed to create or destroy the suction or vacuum.

There are two hooks or catches 1055 and 1011 which are located adjacent to the punch and which are supported adjacent to` the anvil about which the metal binding whether a single or double strip or two strips is adapted to be termed to substantially the shape of the open end of the box form. These hooks are adapted to sustain and hold the ends of the binding metal, the hook or catch 103 being yielding and the hook or catch 101- being normally fixed. There may be as many of these hooks of either the yielding or fixed kind or both kinds' as desired. The hook 103 has an elongated shank portion 105 which is adapted to fit into a circular socket 106 and is pivoted, at 107, at the inner portion of the socket 106 to adapt the outer or hooked end 108 to move up-and-down. The hooked end 108 has a lip 109 which is adapted to engage under one edge of the metal binding and the shank 105 of the device is provided with a slot 110 which is adapted to form a seat for a part 111 of a spring 112. The socket piece 106 is cut away to permit proper up-anddown movement of the hook 10o and is held therein against outward movement byone end of a plate which is held in place by a fiat screw or otherwise. At the inner end the socket piece is adapted to abut against the head of a screw 113 by which the position of the socket 106 may be determined. As one free end of the metal binding is forced about the anvil, it will raise the hooked end 108 to pass by the same and when against the anvil the end 108 will be forced downward and the lip 109 will engage under the lower edge of the binding. The other free end of the binding during the folding operation about the anvil is adapted to have its free end forced downward by a cam 114, Figs. 16 and 20, located on one of the clencher levers S8 in substantially the same manner as described in the application herein referred to, the free end of the strip being forced down far enough to pass under the free end of the binding held by the hook 103 and to enter a recess 115 between the anvil and the lip 116 of the end 117 of the hook or catch 101. At this time the end of the binding will overlap and when the plunger mechanism has been operated as already described, the 'compression of the metal binding to grip the upper edges of the box form will cause the edge held by the lip 116 to pass therefrom so that the completed box may be stripped from the punch without the hook 10e or the hook 103 interfering in any way with the metal binding. The hook 1041- has a shank 118 and is held in a square box 119. This box fits a similarly shaped socket located over the former or anvil 66 and said box is adjusted outwardly by means of a screw 120. rThe box 119 has one edge thereof provided with a tapered recess and adapted to engage this recess is a tapered screw 121 by which the box is held against removal. The metal binding is thus held in position to receive the upper edge of the box form during the upward movement of the die and punch, and

as soon as the binding has been clenched to the box form and the jaws 91 receded from their clenched position, the die is lowered.

The die waits for the box and the punch and die go down together, the die wings 26 remaining folded around the same during the descent of the die. This condition exists until the die bottom is down and the box or basket .is lodged in the holding members 9st, after which the wings quickly open fiat. This folded up relation of the wings in the descent assists materially in stripping the box from the punch.

If the machine is automatic the turret or holder 10 carries the box or basket to an ejector. Y

It is desirable that the four folding wings or members of the die be independently adjustable so that they will coperate properly with relation to the punch and the anvil.. This means of adjustment may be of any suitable kind. As shown, Figs. 5 to T, the arms are arranged in pairs and spaced apart at their upper ends by a spool 122 and are held in such spaced position by a screw 123, a tube 121 serving as a shaft or pivot for connecting the arms 32 to the wings 26. The links 36, there being two for each wing, are held to a spool or spacer 125. rThe spacer 125 has threaded portions 126 on which are spanner nutsV 127, the latter having recesses to permit the shank of a screw 12S to engage the same, the shank of the screw passing into one of the links 36 thus preventing the nuts from unscrewing. The spool or spacer oscillates upon an eccentric pin or shaft 129 which is held against rotary movement in the arms This shaft 129 has one end provided with a nut 130 and its other end with a cap or collar 131. This cap or collar is pro-vided with a plurality of openings 132 in one of which is adapted to pass a screw 133, the shank of which is screw-threaded and engages an aperture in one of the arms 32, thus the shaft or pin 129 may be variously positioned sothat the arms or links 32 may be adjusted relatively to the die.head 17 in order that the wings may have the right relation to the anvil and to be moved for adjustment independently of each other. The eccentric shaft or pin 129 may have an oil passage 1.34 whereby the spool or spacer 125 may be properly lubricated.

If it is desired to remove the anvil 66 and head 65 for repairs or other purposes, this may be done very readily by releasing the screws 135 which hold the tube S0 to the sleeve 136 which supports the anvil. The lower end of the tube is threaded and engaging said threaded end is a Spanner nut 131. By removing the pin 77, the presser foot may be removed and the punch' 63 may be removed which will release the punch member 611 so that the anvil may be removed and afterward reinserted in the machine as d esired.

The sleeve 13S serves as a bearing for the reciprocatory tube 135, but is intended more particularly for a stop for the upward return of the anvil head (if). This stop being adjustable, allows the wire rim or metal bindingI which is held on the anvil and not yet clenched on the box body to bear di Pferent vertical relations to the clenching jaws 91 and thus affects the elenching of the binding either high or low on the side of the rim or binding itself. This allows of easy adjustment to` cause the jaws 91 to clench the lower edge only of the U-shaped metal rim on to the wood shooks leaving the npper or top portion of the section of the shaped binding and wood unfiattened. By this means, a novel method of making a very strong and practical fastening of the metal to the wood is secured. rEhe shape of this fastening is on the principle of the engagement of a dovetail, as at 1882, Fig. 10, and allows the wood to shrink awry from the metal and yet not pull out of the dovetail in the metal. Wooden shocks, it might be mentioned, have to be worked in a damp state and always shrink thereafter, especially when made of sweet gum. The adjustment of the sleeve 138 is secured by turning the same by means of spanner slots 139 and then setting up the lock nut 1&0, said sleeve 138 being threaded at its upper end 14:1 and engaging a threaded bore 1&2

in the frame 90. The lower end or stop end 143 engages with a portion 1th of the head G5 for the anvil 66, there being a clearance space to allow adjustment between the head and the stop end 14: rThe head {35 and the anvil are moved to its lowered position against the tension of the spring 85 by the sleeve 92 to place the anvil in alinement with the folding jaws of the metal bending mechanism, the anvil being raised by the spring 85 as the sleeve is elerated to move the clenching` levers S8 and jaws 91 to clench the binding to the box forni.

l/Vhile the anvil and some of the parts cooperating therewith are shown in more or less detail, these parts as well as the mechanism for bending the metal rim or binding about the anvil relate more particuf larly to metal bending and form only in a general way or broadly a part of the invention of this application. complete descriptien, therefore, et such parts is thought unnecessary. lt might be well to mention however, that the head G5 has ledges 111-5 which serve to keep thoshooks when folded into box forni from pushing the rim or binding up off the anvil The casting 1&6, lfig. 10,

has bosses 147, if ig. 141;, at its four corners and said bosses have apertures in. which areI pivot pins 1-1-8 for the folders of the bending mechanism to swing around. rthere are also bending edges 1li/E), iig. 16, adapted to cooperate with the folding means to form the corners of the rim or binding.

All of the hollow pins may be made to serve as oil reservoirs by closing the ends thereof with plugs 150, one of which is provided with a vent or oil opening. The pins 1%, Fig. 5, are split back to receive tapered pins which, when the latter are driven in, spread the ends of said pins making a tight fit in the ears of the wings 26. One of tho plu 150 of each pin may have a vent or oil opening 1:51, the vent or oil. opening of the plug being positioned so that the hollow pi n or shaft may be filled about two-thirds full of oil. The plugs may be removed by inserting a rod through the opening 151 to drive out the solid plug and then the vented plug may be driven out from the open end of the pin. rljhe eccentric pins 134imay have threaded plugs in their ends, one plug of each pin having an oil hole and the pins 31triay also have similar or other plugs as well as the pins 89 of the clencher levers, there being an outlet opening in each instance for the oil to pass to the bearings.

From the foregoing, it will be evident that oii'ective means are provided whereby boxes or baskets of various sizes may be made and a metal binding applied; that simple means is irovided whereby cross-grained shocks may be utilized and folded without breaking at the point of fold; that simple means is provided whereby irregularities in the lengths and thickness of the shocks may be compensated for; that effective die and punch mechanism is provided in which the parts are properly adjustable with relation to each other; that said parts are readily accessible for repairs or for other purposes; that simple and etlicient pneumatic means is provided to assist in stripping` the box when completed from the punch; and that said mechanism is of such a character that parts thereof are adapted for use in connection with an entirely automatic machine or in a machine which is only partly automatic or of a h and-opera tive kind.
